Filed: 1985-01-11
Abstract: PURPOSE:To obtain good remote control regardless of the presence of inclination by performing automatic correction based on the information detected by the inclination detecting means of a car body so that the actual travel speed is made near the target travel speed. CONSTITUTION:Under a remote control operation, a car is controlled to change its speed by a motor with a reduction gear as a travel speed changing actuator, the speed change operation position by the motor 6 is detected by a potentiometer R3, and the detected information is fed back to a control device 7.

Title: Control method for decoding signal
Inventor: MORI FUMIHIKO
IPC: G06F12/06
Filed: 1989-01-11
Abstract: PURPOSE:To prevent malfunctions with control of a decoding signal by using a decoding signal control circuit consisting of a flip-flop and a gate means which defines the decoding signal with the output of the flip-flop and sending the decoding signal to a peripheral device after the output of data is decided. CONSTITUTION:A decoding signal control circuit 6 set between a decoder 4 and a register 5 consists of a flip-flop 61 and a NAND gate 62 serving as a gate means. The flip-flop 61 is synchronous with the clock signal received from a CPU 1 and also turned on ad off by an inverted signal set in an address latch enable state. The gate 62 receives a decoding signal from the decoder 4 and secures NAND between the inverted signal and the Q output of the flip- flop 61 to output a new decoding signal to the register 5. Then the decoding signal is delayed by the flip-flop 61 and outputted in response to a decided data signal coincident with the clock of a CPU. Thus the data obtained after selection of a device is always fixed, without fear of producing any malfunction.
